Air Conditioning
#
(Air Conditioner): Press this button on the climate
control panel to turn the air conditioning compressor on or
off. An indicator light to the right of the button will come on
to show that the air conditioning is on. This button has no
control over the air conditioning compressor when in the
other modes. The instrument panel brightness control
may have to be adjusted to the highest setting in order to
see the indicator. See Instrument Panel Brightness on
page 3-17 for additional information.
On hot days during the vehicle’s initial start-up, open
the windows to let hot inside air escape; then close
them. This helps to reduce the time it takes for
the vehicle to cool down. It also helps the system to
operate more efficiently.
For quicker cool down on hot days, do the following:
1. Select the vent/outside air mode.
2. Select the recirculation mode.
3. Select the air conditioner.
4. Select the coolest temperature.
5. Select the highest fan speed.
Using these settings together for long periods of time
may cause the air inside the vehicle to become too dry.
To prevent this from happening, select the vent mode
once the interior of the vehicle is cooled.
The air conditioning system removes moisture from the
air, so sometimes there may be a small amount of
water dripping underneath the vehicle while it is idling
or after the engine is turned off. This is normal.
Recirculation
h
(Recirculation): Press this button on the climate
control panel to activate the recirculation mode. With
this selection, inside air is recirculated into the vehicle
along with some outside air. This mode reduces
outside air and odors from entering the vehicle. It may
also help to heat or cool the air inside the vehicle
more quickly.
An indicator light to the right of the button will come
on to show that the recirculation mode is on. The
instrument panel brightness control may have to be
adjusted to the highest setting to see the indicator.
The recirculation mode has a timer. After five minutes,
the system’s air inlet door will move slightly to allow
for ten percent fresh outside air to maintain interior air
quality. The only way to reset the system to full
recirculation is to restart the five minute timer by
selecting vent/outside air and recirculation again.
